PA is very slow in loading this file (“reading files…”)
and it takes a long time extracting single files from
this archive.

Few files in this archive are broken and PA stops from extracting the whole archive with an error.

Which bugs me: the 7-zip file manager is doing fine with this archive.
It loads it fast and extracting single files takes just a few seconds. If I extract the whole archive it just skips the broken files and continues with a hint.
